Integrated smart power devices are becoming increasingly crucial in automotive systems due to their ability to combine power management with advanced diagnostic and protection features. When a fault occurs, these features enable the connected control unit to react promptly and effectively, protecting both the vehicle and its occupants. Smart power devices are often responsible for critical tasks within a vehicle and are gradually replacing conventional components such as fuses and relays, and switches.

Electronic fuses, a prominent type of smart power device, are particularly remarkable for their reliability under harsh environmental conditions, including high operating temperatures and mechanical stress. Additionally, they have to withstand various forms of electromagnetic interference (EMI) that can affect their normal functionality. This is especially crucial in safety-critical applications like airbag control modules or Anti-lock Braking Systems (ABS), where precise operation is vital to avoid hazardous conditions and ensure functional safety.

Testing Procedure for EMI

To ensure the correct operation of electronic products, they need to be tested for electromagnetic emissions that may negatively affect nearby equipment. These emissions fall into two categories:

• Conducted noise, which travels through supply or data/control cables.
• Radiated noise, which propagates through free space.

CISPR 25 is the standard developed for vehicles and boats to protect on-board receivers from such emissions. It outlines both limits and methods of measurement for equipment on board.

Conducted emission limits typically cover a frequency range of 150 kHz to 200 MHz, although this range may extend down to 9 kHz. The limits are defined in terms of average, quasi-peak and peak values.

Peak detection retains the peak value of each harmonic in an emitted signal, indicating the worst-case scenario. Average detection provides the average amplitude of each signal component across its period. Quasi-peak detection weighs each component based on its repetition rate: the faster the repetition rate, the higher the weight given to that component.

The output response of the three detectors to two similar pulsed signals is shown in with the top one having a higher repetition rate.

The above picture shows that the quasi-peak detector has a higher voltage output when the event occurs more frequently.

To determine the conformance of the Equipment Under Test (EUT) with the specified CISPR 25 limits, the following guidelines should be followed (Fig. 2).

In all cases, the EUT should conform to the average limit. For frequencies where both peak and quasi-peak limits are defined, the EUT should conform to either the peak or the quasi-peak limits, as specified in the test plan. For frequencies where only peak limits are defined, the EUT must conform to the peak limit.

For CISPR 25, emission limits are divided into Class 1, 2, 3, 4, and 5 products, specifying how to measure the noise using peak, quasi-peak, and average detection methods (Tabs. 1 and 2).

LW stands for Long Waves

MW for Medium Waves

SW for Short Waves

TV Band I for TeleVision broadcast Band 1

CB for Citizens Band

VHF for Very High Frequencies.

The testing procedure ensures that both peak and average measurements are checked for compliance with Class 5 standards. If any measurements fail, the EUT is evaluated against a lower class.

The conducted Electro-Magnetic Emission (EME) is the noise current generated by the EUT that propagates through the harness to other components/systems or power grid. This noise current can be measured using either the voltage method or the current method.

The voltage method is carried out with the measurement setup displayed in Fig. 3.

LISN stands for Line Impedance Stabilization Network.

The experimental data have been collected for the STi2Fuse product VNF9Q20F, which is a 4-channel monolithic electronic fuse fully programmable through serial peripheral interface (SPI). This device embeds sophisticated digital protection and diagnostic mechanisms, which include a unique i2t feature for harness protection.

The following testing conditions have been considered:

• VBAT = 13 V
• TAMB = Room temperature
• All channel in Fail Safe mode (off)
• Channel 2 driven by direct input with DC (5 V) and PWM (100 Hz, 50% duty cycle) loaded with 27 W + 5 W bulbs.

When channel 2 is turned on and it is driven by direct input with 5 V DC voltage and a PWM signal with 100 Hz frequency and 50% duty cycle, the noise detector measurements for peak and average methods are shown in Fig. 5 and compared with CISPR 25 limit relevant to class 5.

The electronic fuse VNF9Q20F is able to pass all the limits imposed by CISPR 25 for both peak and average limits in class 5.

The EMI behavior of a smart electronic STi2Fuse device has been investigated, demonstrating compliance with the CISPR 25 standard under class 5 specifications.

The STi2Fuse products are critical components in modern vehicles, providing overcurrent protection and ensuring the safe operation of electrical circuits. Compliance with the CISPR 25 standard, particularly under class 5 specifications, is essential for these devices to ensure they do not interfere with other components and equipment within the vehicle.

As artificial intelligence (AI) adoption accelerates, the urgency to protect AI ecosystems grows proportionally. In 2025, the world will witness a concentrated push to address critical concerns surrounding the security of Large Language Models (LLMs) and other advanced AI systems. These efforts will focus on safeguarding data confidentiality, ensuring integrity, and upholding privacy, which are essential to sustaining innovation and trust in AI technologies.

The Rise of AI and Its Risks

AI technologies, particularly LLMs, have revolutionized industries with their ability to process vast amounts of data, generate human-like text, and make intelligent predictions. However, their immense potential also introduces vulnerabilities. Cyber threats targeting AI systems are becoming more sophisticated, with adversaries exploiting weaknesses to steal intellectual property, manipulate outputs, or compromise sensitive data. For instance, adversarial attacks can subtly manipulate input data to mislead AI models, while data poisoning can corrupt training datasets, leading to flawed or biased predictions.

Additionally, as LLMs like ChatGPT or GPT-4 are deployed widely, the potential for misuse grows. These models, if not adequately safeguarded, could be manipulated to generate harmful content, leak proprietary information, or amplify misinformation. Thus, securing AI systems is no longer an afterthought; it is a fundamental requirement for ethical and reliable AI deployment.

Data Confidentiality and Privacy

Data confidentiality is at the heart of AI security. Training LLMs often requires enormous datasets, some of which may include sensitive or proprietary information. Ensuring that this data remains secure and private is a complex but crucial challenge. Robust encryption protocols, federated learning, and differential privacy techniques are emerging as key solutions. These methods enable AI systems to learn from data without exposing individual records, thereby reducing the risk of data breaches.

Federated learning, for example, allows models to train across decentralized devices without transferring data to a central repository. This approach not only enhances privacy but also minimizes attack vectors, as no single point of failure exists. Meanwhile, differential privacy adds statistical noise to datasets, protecting individual data points while preserving the overall utility of the model.

Ensuring Model Integrity

Model integrity is another critical focus area. Attackers may attempt to tamper with the parameters of an AI model to alter its behavior or introduce biases. To counteract this, organizations are turning to techniques like robust model architectures, regular audits, and tamper-evident mechanisms. Blockchain technology, for instance, is being explored to maintain immutable records of model versions, ensuring any unauthorized modifications are detectable.

Furthermore, explainable AI (XAI) is gaining traction as a means to enhance model transparency and trust. By making AI decision-making processes interpretable, XAI can help identify anomalies or unexpected behavior that might indicate tampering or misuse.

A Multi-Stakeholder Approach

Securing AI models requires collaboration across industries, governments, and academia. Policymakers must establish clear guidelines for AI governance and data protection, while researchers and developers work on advancing technical safeguards. Companies deploying AI systems must prioritize regular security assessments and adopt best practices for risk management.

Public awareness also plays a vital role in fostering responsible AI use. Educating users about potential threats and mitigation strategies can help minimize risks associated with AI adoption.

Conclusion

As we move into 2025, securing AI ecosystems will be a defining challenge for the tech industry. By addressing issues of confidentiality, integrity, and privacy, stakeholders can build robust AI systems that not only drive innovation but also inspire trust. The future of AI depends not only on its capabilities but also on the strength of the safeguards we put in place today.

Digitizers by Spectrum Instrumentation used to detect extremely small and fast nerve signals

For controlling prosthetics, the body’s signals must be detected to move the artificial limb. At the moment, implanting electrodes is the most common technique but this is invasive and electrodes can deteriorate or move position. A completely different approach is now developed by the multidisciplinary consortium QHMI in Stuttgart, Germany, using quantum sensors to detect the incredibly small and fast nerve signals. The ultrasensitive quantum magnetometers will be carried outside the body measuring the neural signals through the skin. At this stage, the scientists are using Spectrum Instrumentation’s ultrafast digitizers (M5i.3357) and Arbitrary Waveform Generators (M4x.6631) to characterize the signals and to finally design the required Application Specific Integrated Circuits (ASICs) and Photonic Integrated Circuits (PICs).

Prof. Dr. Jens Anders of the University of Stuttgart, who is in charge of the project ‘Cluster4Future QSens’ and a leading scientist of the QHMI consortium, explained, “This is one of the first real-world applications for quantum sensor probes as there is no other way to non-invasively detect such tiny magnetic changes that are in the order of 10 to 100 picoTeslas for muscles: that is six orders of magnitude smaller than the Earth’s magnetic field. Our tests show that our sensors are sensitive enough that they can detect neural signals to muscles through the skin. Even a small amount of remaining, say, lower arm muscle can in principle be used for this. We are working on even greater sensitivity for the femtoTesla magnetic changes we need to measure to detect signals within the brain without breaking the skin.”

At the heart of this technology is an optically detected, magnetic resonance (ODMR) device made of a tiny slice of diamond. The diamond is doped with so-called nitrogen-vacancy centers (NV centers), which have a net electron spin and, therefore, behave like tiny bar magnets. When green laser light is shone on them, they produce a red fluorescence signal. By applying a suitable microwave magnetic field, this fluorescence signal is very sensitive to external magnetic fields, which can be used to measure neural signals with utmost precision.

The microwave magnetic fields required to control the NV center spins are generated using suitable coils driven by a microwave transmitter. The baseband signals for this transmitter are generated using an Arbitrary Waveform Generator (AWG) to provide the required phase and amplitude modulation of the carrier signal that make the excitation signal more robust against experimental nonidealities. The resulting fluorescence signals, which carry the information of the neural magnetic fields, is then captured by a photodiode, amplified, filtered and digitized for advanced signal processing.

Spectrum’s cards were chosen by the team for several reasons. First, they have an extremely high dynamic range and good noise performance which is vital for such tiny signals. Second, they are very fast, so they can capture the fast signals associated with advanced pulsed excitation schemes, which can require bandwidth beyond 100 MHz. Third, they offered a great value in terms of performance / price. And lastly, the five-year warranty provides peace of mind that a critical component of the research is good for five years as it is almost impossible to obtain funding to replace a failed piece of equipment.

The quantum sensor probes are currently matchbox-sized and, in the future, will be around one cubic centimeter and go to a control box that is roughly the size of a large matchbox that houses the processing electronics and the battery. The aim is to use microelectronic and photonic integration to shrink the control box further and extend the battery life to give a day of use before recharging. It is hoped that prosthetics will start becoming available in three to four years.
